Further study shows that the circles were outside the left hand side of the 
scree.
A mystery remains: Why wasen't the rectangle resized to fit the contents?
To summarize:
         #leftToRight -> #rightToLeft  OK
         #rightToLeft -> #leftToRight  OK
         #leftToRight -> #topToBottom  OK
         #topToBottom -> #leftToRight  OK
         #topToBottom -> #rightToLeft  Rectangle becomes a square
         #rightToLeft -> #leftToRight -> #rightToLeft  OK again.

More fingertrouble?
